Removed Entries



I’ve noticed an entry that I previously used in a dataset no longer exists (mp-23023). Is there some way to see why an entry was removed from the materials project? If the data was considered untrustworthy in some way, it would be good to be able to see details.

(My apologies if the answer is already somewhere on the site and I simply couldn’t find it!)

Thank you,


Hi Logan,

This appears to be a bug on our end. This entry is in our system but when translating from the calculations to the website document, something went wrong. I’m going to investigate this tomorrow. This should be back by the end of the month when we release an update to the DB.
